We are specifically and deliberately going to do without the Smith chart today and look at some transmission line properties from a very basic perspective. Consider a transmission line, a coaxial ...

Known as EIS, Electrochemical impedance spectroscopy is an increasingly common non-destructive technique that is used to analyze and identify a material’s physicochemical properties, especially at the ...

If you are an old hand at RF design, you probably have a good handle on matching impedance. However, if you are just getting started with RF, [FesZ Electronic]’s latest video series on lossless ...

We always enjoy a [FesZ] video and we wonder if the “Z” stands for impedance? That’s the topic of his latest video series: measuring impedance with LTSpice. Of course, he also does his usual thorough ...

Bioelectrical impedance analysis is a noninvasive and rapid method for estimating body composition, including body fat and muscle mass. Previous studies have indicated that bioelectrical impedance can ...

Download this article in PDF format. Jacques and Pierre Curie, French physics, discovered the piezoelectric effect in 1880. When some solid material is mechanically compressed or stressed, the ...

The EA-BIM 20005 battery impedance meter from Tektronix uses electrochemical impedance spectroscopy (EIS) across 20 channels to characterize Li-Ion battery cells. With industry-standard interfaces and ...
